For pressures up to about 50 bar the equation of state PV = n (RT- (0.072 L/mol) P) with P in bars as well as V in liters for CO2 at 100°C is adequate. Compute the fugacity as well as the fugacity coefficient of CO2 (g) at 100°C as well as 37.5 bar.
Calculate the of the solution that results from each of the following mixtures: Part A - 55.0 mL of 0.15 M HCHO2 with 70.0 mL of 0.13 M NaCHO2
When the concentration of Zn2+ ion is 0.45 M, the measured voltage of the Zn-Cu zell is 0.40 V. What is the Cu2+ ion concentration
What mass of precipitate will form if 1.50 L of concentrated Pb(ClO3)2 is mixed with 0.400 L of 0.260 M NaI. Assume the reaction goes to completion.
Deduce the structure of the molecule with the molecular formula C3H6 with a C13 NMR delta peak value of 27.8
Synthetic polypeptides can assume an helical structure under appropriate conditions. Indicate whether polylysine and polyglutamate form an helix or a disordered structure at the indicated pH values.
The rate constant for a certain reaction is = 4.60×10-3 s^-1. If the initial reactant concentration was 0.900 M , what will the concentration be after 5.00 minutes
A titration is carried out to determine the concentration of the acid in an old bottle of aqueous HCl whose label has become unreadable.What is the HCl concentration if 32.1mL of 0.250M NaOH is required to titrate a 30.0mL sample of the acid
Sometimes the structure of phosphoric acid is written with single bonds to both the OH groups and to the oxygen atom; other times the bond between the P and the O is shown as a double bond. The "truth" probably lies somewhere between. Explain
What amount of solid NaOH must be added to 1.0 L of a 0.12 M H2CO3 solution to produce a solution with {H} = 3.0×10-11 M? There is no significant volume change as the result of the addition of the solid.
Explain why do we need potassium carbonate before distillation? I did an ethanol from sucrose lab as well as the TA had to put potassium carbonate in the mixture before we utilized fractional distillation to separate the 3 liquids
